主要特色
True-RMS Meter with Single-Channel Scope
500 kHz Scope + Automotive DMM
Combine voltage, current, resistance, frequency, diode, continuity-related, ignition-pulse, and basic waveform checks with a single-channel oscilloscope. The scope has stated 500 kHz analog bandwidth, a 1mS update rate, practical sweep-time and vertical-scale ranges, and one-button automatic waveform display.
DC / AC Voltage
Measure automotive-circuit voltage up to DC 1000V and AC 700V within the selected input, probe, and CAT conditions.
DC / AC Current
Measure 0-200mA current; the comparison range also lists 0-20A. The feature states 20 A maximum current and 10 A continuous current. Use the specified terminal, fuse, and lead for the selected mode.
Resistance + Diode
Measure resistance across the listed 0–1MΩ range and test diodes; the meter gives an audible alert when detected resistance is too low.
頻率測量
Measure frequency signals from 1Hz to 1MHz for common automotive electrical-signal checks.
Auto Range + True RMS
Select the measurement mode and connect the test leads; DM301 automatically selects a suitable range and supports True RMS readings.
2.8-Inch Adjustable Display
Adjust the brightness of the 2.8-inch color screen for clear, intuitive viewing in different workshop and vehicle-side environments.
多語言界面
Supports English, French, Portuguese, Polish, Spanish, Japanese, Russian, Italian, German, Dutch, Korean, Chinese, and Traditional Chinese.
SD Card Software Upgrade
Copy the application update file to an SD card and upgrade the instrument through the card.
可選鋰電池
DM301 accepts a compatible optional lithium battery. Batteries are purchased separately, and dry batteries must not be charged through the device.
Controls, Connections + Stand
Front-panel keys, the marked button area, labeled measurement and accessory connections, connector-position reference, and rear bracket keep operation accessible and support upright viewing.
Automotive Signals + Safety Boundary
Select engine cylinder type and ignition mode to help calculate engine speed, and use the scope or measurement modes to observe ignition, camshaft, crankshaft, wheel-speed sensor, oxygen-sensor, and other fuel-engine or low-voltage signals. Use only documented low-voltage or properly isolated measurements within the selected input, probe, and CAT conditions; do not probe an EV traction circuit or motor power bus without separately rated HV procedures and equipment.
Workshop Circuit Testing
Use voltage, current, resistance, frequency, diode, and continuity-related checks for vehicle electrical-circuit troubleshooting.
Portable Field Kit
The handheld 85 × 190 × 33mm body, flashlight, rear bracket, and plastic toolbox support field diagnosis on trucks, sedans, buses, electric vehicles, and other vehicle types while storing the unit and accessories and helping protect them from drops and impacts.
3年保固支持
主機:三年保固。標準配件:一年保固。保固政策。
服務工作流程
Choose Meter or Scope for the Signal
Define the Measurement
Use the wiring diagram to identify the expected signal, reference point and safe measurement mode.
Inspect Leads and Ratings
Confirm the instrument, terminal, fuse, lead and probe ratings for the selected task before connecting.
選擇模式
Choose the supported voltage, current, resistance, continuity, frequency or other model-specific function and start on a safe range.
Probe the Circuit
Connect to the correct reference and test point without bridging terminals; use back-probing accessories only where appropriate.
Save and Compare the Reading
Save the value and operating state, then compare the reading with the vehicle specification.
安全使用
Protect the Input and Ground Reference
Dry Battery Option
DM301 can use 4 × 1.5V dry batteries according to the battery compartment requirement.
Do Not Charge Dry Batteries
Only a compatible rechargeable lithium battery can be charged through the device. Do not charge dry batteries.
不含電池
DM301 / DM303 are shipped without batteries. Please purchase compatible batteries separately before use.
可選鋰電池
A compatible lithium battery can also be installed by the user. Use the battery style shown as a reference before purchasing.
Interpret Multimeter and Waveform Results in Context
Use the input limit, terminal, fuse, lead and probe specified for the selected mode. Display counts, voltage range or waveform bandwidth do not extend the meter to an unlisted CAT or EV high-voltage task.
